## Member Function Documentation

template<class ITERATOR, class DIFFERENCE>
value_type const& operator() | ( | ITERATOR const & | i,
|  | DIFFERENCE | d |
| ) |  |  | const

Get value of the red component at an offset

template<class ITERATOR>
value_type const& operator() | ( | ITERATOR const & | i | ) | const

Get value of the red component

template<class V, class ITERATOR, class DIFFERENCE>
void set | ( | V | value,
|  | ITERATOR const & | i,
|  | DIFFERENCE | d |
| ) |  |  | const

Set value of the red component at an offset. The type `V` of the passed in `value` is automatically converted to `value_type`.

template<class V, class ITERATOR>
void set | ( | V | value,
|  | ITERATOR const & | i |
| ) |  |  | const

Set value of the red component. The type `V` of the passed in `value` is automatically converted to `value_type`.
